What is the proper section for discussion about services?

[examplens]

A question for the forum moderators, and maybe others too if they have a good suggestion.
I would like to open a discussion about some specific crypto services, I would like to hear other opinions and experiences, but I don't see where would be the most appropriate place for that.

I wouldn't say that they belong to the Technical board, but all other sections deal with a general discussion and are almost crowded with endless topics, What is expected from the bull run, halving, will Bitcoin reach the price of xx...

The two closest boards have a description
- Cryptocurrency discussions - Altcoins & Cryptocurrencies general discussion -no speculations & no ANN
- Bitcoin Forum - Talk about bitcoin BTC - Ecosystem. News, community, mining, technical, etc...

For example, where is it appropriate to start a topic from a specific service from the "ad network" or "payment gateway" zone?
